Abstract: The present invention relates to a screen protection cover configurable on a handheld device (E.g., a smartphone). The cover includes a transparent cover body, an adhesive member and a chemical agent(s). The transparent body is configured to cover a display screen of the handheld device. The adhesive member is provided on a rear surface of the cover for removably attaching the cover onto a front surface of the display screen of the handheld device. The chemical agent is adapted to change its physical property to alert the user about a potential infection when one or more biological agents transmitted from the user's body come in contact or in proximity to the cover. The physical property includes a color and/or a smell. The user is required to conduct a medically proven disease diagnosis test upon receiving a visible or sensory alert generated by the cover.

Abstract: A remote controlled fan is operated by a hand held remote control which controls the power, speed of fan rotation, oscillation of the fan, and movement of the fan. The fan operates on either AC power or batteries. The fan can move forward or rearward or rotate about its vertical axis in response to signals from the remote control unit.
